The performance of the new DIGAZFEN-I inhibitor for hydrogen sulfide corrosion in saline-hydrocarbon media, including the components (pyridine bases and fatty-acid aminoethers), was tested. Inhibition was determined gravimetrically on steel St3 in 3% NaCl solution and A-72 gasoline containing 1.5-2 g/liter hydrogen sulfide. Hydrogenation was determined indirectly from the plasticity changes in U9A steel strip specimens which were subsequently tested to failure. In parallel, potentiostatic measurements were made in 3% NaCl saturated with hydrogen sulfide with Armco iron. The inhibitor increased the hydrogen overvoltage and reduced the dissolution current while it also retarded both the anodic and cathodic processes.
